Review: Outrageously overpriced should be supplied - If these are so needed they should be supplied with the power washer. It seems outrageous to pay the same price as a basic one to safely use your power washer. Mine is a decent one and this was still half the price of it Review: Used to prevent backflow - Difficult to know if this is actually working but have installed on my kitchen tap when using with my Nilfisk pressure washer to prevent backflow into the main water supply. Very expensive for what is essentially just a piece of small plastic. ## Features - BACKFLOW VALVE: The backflow preventer removes the risk of contaminated detergent or water flowing back into the main drinking water supply. - COMPATIBILITY: 3/4" connection male/female - NILFISK STORE: Discover more accessories by visiting our desertcart brand store.

It seems outrageous to pay the same price as a basic one to safely use your power washer. Mine is a decent one and this was still half the price of it ### ⭐⭐⭐⭐ Used to prevent backflow *by D***L on 7 October 2023* Difficult to know if this is actually working but have installed on my kitchen tap when using with my Nilfisk pressure washer to prevent backflow into the main water supply. Very expensive for what is essentially just a piece of small plastic. ### ⭐⭐⭐ Fits a standard UK outdoor tap hose fitting *by E***R on 23 July 2020* There is not a huge amount to be said about this product other than it fit my outdoor tap and hosepipe well. The instructions with the pressure washer suggest this is essential but I don't even know if this was a necessary purchase because we might have a double check valve plumbed in already. However, as I have used the pressure washer for drain unblocking, I didn't really want to take the chance. Overall design and build quality etc. are ok but seems very expensive for what it is. ## Frequently Bought Together - Nilfisk Backflow Valve Comp.
